Fig. 3: Genetic relationship of Deinanthe species/populations.

a Maximum-likelihood phylogenetic tree of Deinanthe individuals inferred based on genome-wide SNP data. Differently coloured tip circles correspond to the geographic regions. Node support values are shown only for those greater than 99. b Geographic distributions of nuclear gene pools estimated by STRUCTURE analysis (Pritchard et al. 2000) based on genome-wide SNP data for Deinanthe species (K = 5). A neighbour‐joining tree showing the relationships of each gene pool are superimposed on the maps. Four regional populations in D. bifida are defined here as Chubu, Kinki, Chugoku, and Kyushu.
